As was the case for 4.2 build 2000, oss will not attach on boot for Solaris 10, so no audio device is available. ossdetect must be run every time a user wants audio. After reboot, the drivers are again unavailable.

The sound is awesome. You know, without oss, Solaris 10 x86 sound is unbelievably bad in VirtualBox guests on Windows hosts. All music and videos run at an erroneously high speed, with terrible quality. With oss, it is FANTASTIC.

Today, sound will work only intermittently in Solaris 10 JDS. It may work for a while, but after I play a sound or .mpg, it will stop, and no further sounds are available until next reboot. After the problem occurs, all mpegs will play only very very slowly, and osstest returns errors on playback with no sound.

Solaris 10 is running as a VirtualBox (3.0.10) guest on a WinXP host. Part of the problem may be the VirtualBox implementation of sound for Solaris guests. Using Windows DirectSound host driver and ICH AC97 controller in Vbox VM settings.

Things seem better now. But a little unstable, which is possibly do to VirtualBox's audio support. I'll report back with problems. Thank you for your help!

I wonder why I had to make the changes you suggested. Is it a problem with the oss Solaris package, or have all the oss-related files become screwed up on my system? I have had trouble uninstalling oss in the past. See:
